MADISON, WI - MARCH 10: Jessica Dias, associate research specialist, at the Wisconsin National Primate Research Center at University Wisconsin-Madison removes a new batch of Embryonic Stem Cells from deep freeze to be thawed before being worked on March 10, 2009 in Madison, Wisconsin. On March 9, 2009 President Barack Obama signed an order reversing the Bush administration's limits on human embryonic stem cell research. Scientists at the University Wisconsin-Madison, who were the first to experiment in finding cures to neurological and muscular diseases through stem cell research, are now hoping to receive federal funding to aid in their work.
